JUBA, Sudan — A confidential United Nations report warns that the invasion by Sudan's military of the contested north-south region of Abyei could lead to "ethnic cleansing" if the tens of thousands of residents who fled are not able to return.
The U.N. human rights report — dated May 29 and marked "Not For Public Citation or Distribution" — said the north's Khartoum government may have carried out a premeditated military plan to invade Abyei when Sudanese Armed Forces, or SAF, troops moved in May 21.
"The SAF attack and occupation of Abyei and the resultant displacement of over 30,000 Ngok Dinkas from Abyei could lead to ethnic cleansing, if conditions for the return of the displaced Ngok Dinka residents are not created," according to the report, which was obtained by The Associated Press on Friday.
The Ngok Dinka is a black tribe that associates itself with Sudan's south. The Ngok Dinka fled Abyei when northern troops and ethnic Misseriya — Arab cattle herders aligned with the north — moved in and looted homes. The U.N. report estimated that between 15 percent and 20 percent of the homes in Abyei were burned in what it called "deliberate destruction" and a violation of international humanitarian law.
"By destroying their homes, looting their properties and inspiring fear and terror, over 30,000 Ngok Dinkas have been forcefully displaced from their ancestral homes, leaving the Abyei area now more or less homogeneously occupied by the Misseriya," it said.
Ethnic cleansing, the report said, is a purposeful policy designed by one ethnic or religious group to remove by violent and terror-inspiring means the civilian population of another ethnic or religious group from certain geographic areas.
The report said that the likelihood that all the Ngok Dinka residents can return to Abyei "is limited," given the massive destruction of civilian property and the occupation of Abyei by northern forces.
North and south Sudan fought a more than two-decade civil war that ended with a 2005 peace agreement that also gave the south the right to vote for independence. That vote passed overwhelmingly, and Southern Sudan is poised to become the world's newest nation in July.
But tensions over Abyei — a fertile land near major oil fields — has raised fears of conflict only weeks before the south secedes.
The north's invasion of Abyei was precipitated by a May 19 attack on northern and U.N. troops by southern soldiers. The U.N. report said two northern soldiers were killed in that attack, which it called a trigger for the invasion but one that appeared to be a "deliberate plan" by the north "as evidenced by the SAF troop build up in the area before the attack," the report said.
The report also called the southern shelling of U.N. peacekeepers a violation of international humanitarian law.
The U.N. is not the first organization to warn that war crimes may have been committed by the Khartoum government's army in the recent Abyei violence.
A U.S.-based project supported by Hollywood star George Clooney published satellite images of the destruction in Abyei after the invasion and called on the U.N. Security Council to refer the invasion to the International Criminal Court.
The Satellite Sentinel Project said a group of former U.S. civilian and military officials had affirmed the group's visual evidence that the Sudanese government had "allegedly committed war crimes during its occupation of the disputed region of Abyei."
David Scheffer, former U.S. State Department Special Ambassador-at-Large for War Crimes, was quoted by the group as saying that the evidence derived from the satellite imagery of the destruction in Abyei "reveals actions that appear to violate the principles of military necessity, proportionality, and distinction — primary pillars of the laws of war."
As tanks rolled into the town and Antonov planes provided air cover for the northern troops and their associated militia forces, tens of thousands of Abyei residents fled south, many on foot, while carrying small children and whatever possessions they could manage.
The U.N. Security Council, on a visit to Sudan when the invasion occurred, called for the immediate and unconditional withdrawal of the Sudanese Armed Forces. But nearly two weeks later northern troops have not left Abyei, and many diplomats, analysts, and even Southern Sudanese officials quietly say that no one has much leverage to force the north to withdraw.
President Barack Obama's Homeland Security and Counterterrorism adviser, John Brennan, held meetings in Sudan's capital of Khartoum this week to discuss deteriorating security conditions around Abyei.
